STNTRxx

The STNTRxx system initialization parameter specifies the level of standard tracing you require for a particular CICS component.

STNTRxx={1|(1[,2][,3][,4])|ALL|OFF}

You identify the component by coding a value for xx in the keyword. You code one STNTRxx keyword for each component you want to define selectively. For a CICS component that is being specially traced, and that does not have its trace level set by STNTRxx, the trace level is that set by STNTR (which, in turn, defaults to 1). You can select up to three levels of tracing, but some CICS components do not have trace points at all these levels.

The CICS component codes that you can specify for xx on this STNTRxx keyword are shown in the following table:

number

The level numbers for the level of standard tracing you want for the CICS component indicated by xx. Level numbers 1, 2, 3 and 4 can be used, depending on the component.

Most CICS components only use levels 1, 2, and 3, and some do not have trace points at all these levels. The exceptions are the SM (storage manager domain) and SJ (JVM server) components, which also have level 4 tracing. This level of tracing is intended for IBM® field engineering staff.

Attention: Selecting tracing levels 3, 4, or ALL for standard tracing for the storage manager (SM) component, or the temporary storage domain (TS), degrades the performance of your CICS region. This is because options 3, 4, and ALL switch on trace flags that are used by the SM domain for field engineering purposes.

SM trace flag 3 deactivates the quickcell mechanism, and SM trace flag 4 forces subpool element chaining on every CICS subpool. Furthermore, after these settings have been activated during system initialization, they cannot be unset, either through a PLTPI program or by using the CETR trace transaction, because they are not used for tracing as such. Thus, a significant performance overhead is incurred if these storage manager trace levels are selected for standard tracing.

For information about the effects of trace levels 3 and 4, see CICS trace.

ALL

You want all the available levels of standard tracing switched on for the specified component.

Attention: Selecting ALL for standard tracing for the storage manager (SM) component, or the temporary storage domain (TS), degrades the performance of your CICS region. This is because ALL switches on trace flags that are used by the SM domain for field engineering purposes.

Selecting ALL for standard tracing for the JVM domain (SJ) component is not recommended. JVM trace can produce a large amount of output, so activate JVM trace only for special transactions (using the SPCTRSJ system initialization parameter), rather than turning it on globally for all transactions.

OFF

Switches off all levels of standard CICS tracing for the CICS component indicated by xx.

Restriction: You can specify the STNTRxx parameter in PARM, SYSIN, or CONSOLE only.
